lll 'lACl-HNE FOR MAKING SHOVEL-HANDLES.

SPECIFICATION forming part Of Letters Patent No. 661,400, dated November 6, 1900.

Application filed April 3, 1900. serial No. 11,32 1. (No model.)

To (LZZ whom it may concern:

Be it known that I, AUGUSTUS R. FEISTEL, residing at Philipsburg, in the county of Center and State of Pennsylvania, have made certain new and useful Improvements in Machines for Making Shovel-Handles, of which the following is a specification.

My invention is a machine for cutting the D-holes in the blanks of shovel and fork handles. A handle-blank is clamped in a vertically-tiltable holder pivoted in a horizontallyslidable carrier or carriage by which it is fed to a rotatable cutter-head. The holder is tilted into vertical position while the cutter is forming the D-hole in the handle-blank and is thrown back to horizontal position as the carriage recedes. The blank is then reversed in the holder and the operation is re- 'peated.

In the accompanying drawings, two sheets, Figure l is a plan view of my improved ma chine. Fig. 2 is a plan view showing the slidable carriage'advanced to the cutter and the shovel-handle blank tilted upward. Fig. 3 is a central longitudinal section on the line 3 3 of Fig. 1. Fig. 4 is a longitudinal section on the line 4 4 of Fig. 2. Fig. 5 includes perspective views of important parts of the machine detached from each other. Fig. 6 is a plan View of a shovel-handle in the form in which it leaves the machine.

A cutter or cutter-head 1 is fixed on the upper end of a vertical shaft 2, (see Figs. 3 and 4,) which is held insuitable bearings 3 3 and provided with a pulley 4 for application of a driving-band. This shaftis arranged in a rectangular slot or opening formed in the horizontal bed 5 of the machine. The shovel-handle blank X is held in a holder 6, which is pivoted in a carriage 7-, adapted to slide horizontally on the flanges 8 of side guides 9, arranged parallel on each side of the aforesaid opening in the bed 5. The said carriage 7 is composed of two bars (see Fig. 5) having internal grooves 10, adapted to receive the flanges 8 of the side guides 9. These grooved bars 7 are connected by cross-bar 7, to which a rack-bar 11 is attached. The said rack-bar slides in a passage or guide-slot 12, formed in the bed or frame 5, and is engaged by a pinion 13, (see Figs. 3 and 4,) which is keyed upon a shaft 14, arranged beneath the oration is repeated.

bed or frame 5 in suitable bearings and adapt ed to be rotated by a hand-wheel 15. In some cases I may dispense with the hand-wheel and substitute a pulley or other device adapted to be acted upon by an automatic reversible motor. By means of such rack-bar and pinion the carriage 7 is advanced toward and withdrawn from the cutter 1 as required in the operation of cutting the D-hole in the handle-blank X.

The holder 6, in which the blank is secured, consists (see Fig. 5) of two parallel internally grooved or flanged bars which are rigidly connected by a cross-bar 6. The bars 6 of the holder are provided exteriorly with hollow trunnions 16, by which it is pivoted and adapted to rotate in the side bars of the carriage 7. One of the bars 6 of the blanlc holder is extended forward and provided with a lateral projection 17, consisting of a pin having an antifriction-sleeve. Such projecjection 17 comes in contact with a fixed and forwardly-curved cam 18, (see Figs. 3 and 1, when the carriage advances, whereby the holder 6 is automatically tilted from the horizontal to the vertical position. Figs. 2 and 1 show the holder 6 with its contained blank X thrown upward to a slight angle from the vertical. As the carriage 7 recedes from the cutter 1 the aforesaid projection 17 strikes upon another cam 19, arranged opposite and adjacent to the first-named cam 18, and said cam 19 being curved rearwardly it serves to throw the holder6 automatically back to its original or horizontal position. The handleblank X is then reversed or turned over and the op- In other words, it requires two forward and backward movements of the carriage 7 and reversal of the blank X to completely form the D-hole in the latter.

For clamping and securing the blank X in the holder 6 during the operation described I provide pins 20, which pass through the hollow trunnions 16 of said holder and are provided with enlarged heads (see Fig. 5) to adapt them for engagement with cams 9 and retractors 9", which form portions or attachments of the side gnide-bars 9,that is to say, when the carriage 7 is in the position shown. in Figs. 1 and 3 the heads of the pins 20 are in contact with the inclines or cams 9 and in the slot 21 of the retraetors 9". In such forced inward and enter the sides of the blanks X, and thus clamp and secure the same in the holder 6. This engagement continues until the carriage recedes, when the heads of the pins 20 again engage the slotted retractors 9 whereby they are withdrawn out of contact with the blank X, so that the latter may be removed from the holder. The punctures or indentations made in the blank X by the pins 20 are at the points where the long binding-rivet is commonly inserted in the completed shovel-handle. It is thus apparent that by the rocking or reciprocating rotary motion of the shaft 14: the carriage 7 is reciprocated and the blank-holder 6 tilted automatically, so that the operation of cut ting the D-hole in the blank is effected rapidly and without any Inanipulationother than that required to reverse its movement, as before described.

Since the cutter begins operating on the blank as soon as the latter rise'sfroin' the horizontal to the vertical, it rounds the grip or cylindrical portion of the handle proper.

The cutter 1 is essentially conical in form and composed of a conical cutter at the top, a less conical cutter at the base, and inter mediate disk cuttersavhoseteethare arranged spirally. I do not, however, restrict myself toany particular construction of the cutter, but propose to employ any suitable form of construction of the same.

I show the two cams or inclines by which the pins 20 are pushed in and retracted as arranged directly opposite and separated by a space sufficient to admit easy passage of the heads of the pins; but I may arrange the cams more widely separated and one in advance of the other.

I intend to include in my invention any form of devices that may be suitable for operating the pins.

What I claim is 1. The combination with a rotatable cutter of a slidable carrier or carriage and means for reciprocating it, a tiltable holder for a shovel-handle blank which is pivoted in said carriage, and automatically-operating means j for tilting the said hold er as it approaches the cutter-head substantially as shown and described.

2. The combination with a rotatable cutter arranged vertically and fixed guides arranged horizontally in suitable proximity thereto, of a carrier or carriage adapted to slide on said guide toward and from the cutter, automatically-operating means for effecting such reciprocating movement, a holder for shovelhandle blanks which is pivoted in said. car'- riage, and automatically-operating means for tilting the blank-holder to bring the blank into engagement with the cutter,substantially as shown and described.

3. The combination with a rotatable cutter of side guides arranged adjacently in horizontal position, a carriage adapted to slide thereon, means forimparting the required movement thereto',and ahandle-blank holder which is pivoted in said carriage and provided with internal parallel grooves for receiving the blank, and having a projection adapted to engage a device adapted to tilt the holder gradu ally into vertical position, the said device being located in suitable proximity to the out ter, substantially as shown and described.

4.. The combination with a rotatable cutter and suitable side guides of a reciprocating carriage, a blank-holder which is pivoted and tiltable therein,and a fixed projection or cam adapted to engage and tilt said holder substantially as shown and described.
